Electric arc protection from head to toe

02 October 2009

PWG has launched a high energy arc kit made from Nomex. The kit, with Arc Thermal Performance Value (ATPV) >40 cal/cm2 and certified to IEC 61482-1-1 and IEC 61482-1-2 class 2, consists of a jacket, trousers, hood and gloves that can be used in conjunction with respiratory equipment.

The material for the high energy arc suit was selected to achieve both high protective performance and maximum comfort.

A combination of two layers of Nomex Comfort was selected plus one layer of Nomex felt. The Nomex Comfort fabric includes Kevlar fibres for improved tear resistance and P140 fibres for permanent antistatic properties. The three layer construction combines high inherent flame and heat resistance with durability and electric arc protection against incident energies up to 40 cal/cm². Fabrics made from Nomex do not burn or melt and, even at relatively low weights per square meter, can withstand the extreme impact of an electric arc.

The weight of the jacket and trousers is just 2.5 kg resulting in a light weight solution with a high level of arc protection.

The protective suit with hood and gloves is certified to EN ISO 11612 for flame and heat resistance as well as EN 1149-5 for anti- static. The safety gloves are tested to EN 407 for thermal protective effect.
